Do I need structural calculations for a villa extension?
Yes. A villa extension adds new structure and load, so the developer and the authority require stamped structural calculations with the drawings, covering the new foundations, columns, beams and slabs, and any connection to the existing villa.
The short answer
Whether it is a ground-floor room, an extra floor or a covered terrace, an extension changes how loads go to the ground. The calculations check the new elements, the existing structure where the extension connects or adds load, and the foundations. They are submitted with the drawings for the developer NOC and the DM, DDA or Trakhees permit.
What you need to know
- Ground-floor rooms: New foundations and walls or frame.
- Extra floor: The existing structure must carry the new floor.
- Covered terraces: Roof structure, columns and foundations.
- Connections: How the new part joins the existing villa.
